Treble vs Bass

When the G-clef is placed on the second line of the stave, it is called the treble clef. This is the most common clef used today, and the only G-clef still in use. For this reason, the terms G-clef and treble clef are often seen as synonymous. It was formerly also known as the violin clef. The treble clef was historically used to mark a treble, or pre-pubescent, voice part. When the F-clef is placed on the fourth line, it is called the bass clef. This is the only F-clef used today, so that the terms F-clef and bass clef are often regarded as synonymous. http://en.wikipedia.org/wiki/Treble_clef#Treble_clef
